WHEEL CONSTRUCTION.

Specification of Letters Patent.

Patented June 4:, 1912.

Application filed May 2, 1911. Serial No. 624,598.

To all whom it may concern Be it known that I, JOHN W. Donn, a citizenof the United States, residing at Lynchburg, in the county of Campbell,State of Virginia, have invented certain new and useful Improvements inWheel Constructions; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to new and useful improvements in wheelconstructions and more especially to detachable wheels for cars, and theobject of my invention is to provide .a wheel which may be easilysecured to the axle of the car in such a manner as to revolve therewithbut which may be easily removed when desired.

A further object of my invention is to provide a wheel of the abovedescribed character which shall be reversible, whereby when one treadbecomes Worn the wheel may be removed and then placed upon the axleagain in the reverse position, thus bringing a fresh tread intoengagement with the rail. And a still further object of my invention isto improve the construction and increase the efliciency of wheels of theabove described character.

With these and other objects in view, my invention will be more fullydescribed, illustrated in the drawings, and then specifically pointedout in the claims, which are attached to and form a part of thisapplication.

In the accompanying drawings, which illustrate a preferred embodiment ofmy invention, Figure 1 is a front elevation of the wheel as applied tothe axle, the axle bearing not being shown. Fig. 2 is a side elevationof the same. Fig. 3 is a section through the line 33 of Fig. 1. Fig. 4is a section through the line firof Fig. 2.

Referring more specifically to the drawings, in which similar referencenumerals designate corresponding parts throughout, 1 designates ingeneral the axle of a car which as shown is provided adjacent its endwith a squared portion 2, each face of which is provided with a radiallyextending socket 3, the positions of each of said sockets and the facesin which they are formed, being identical.

The wheel 41 as'best shown in Figs. 1 and 2 of the drawings, consists ofa hub member 5, a web memberfi and a tread member 7, said latter memberbeing divided into two independent treads by means of the centrallylocated annular flange 8. The hub member 5 is provided with a squaredbore 9 adapted to engage with the squared portion of the axle andadjacent either end of the hub and extending radially from each face ofsaid bore is a bore 10, each of said bores terminating in a recess 11formed in the face of the web. These bores are so positioned that thebores upon one end of the hub will register with the bores of the axlewhen the wheel is in one position, while the bores upon the other end ofthe hub will register with the bores of the axle when the wheel is inreversed position. Each recess is provided with a bore extendingvertically through the web of the wheel, said bore being designated bythe numeral 12, and as shown in the drawings these bores are slightlyspaced away from the outer end of the bores 10.

The wheel as above described is secured upon the axle by means of pins13 which are passed inwardly through the bores 10 until their inner endsare seated in the sockets 3 of the hub, in which position the heads 14of the bolt are seated in the inner portions of said recesses,terminating adjacent the bores 12. Additional pins 15 are then passedthrough the bores 12 until their heads 16 are seated in the recesses 3,bearing against the heads 14: of the pins 13. These latter pins asshown, extend a slight distance beyond the Web of the wheel and each isprovided with a perforation 17 adapted to receive a cotter pin or othersuitable fastener 18, by which means they are firmly secured inposition.

It will be seen from the above description that the wheel is firmlysecured to the axle by means of these pins in such a manner that itcannot possibly work loose, and at the same time the wheel may bereadily removed and secured in reverse position. It will also be seenthat the strain upon these pins is comparatively slight, as their onlyfunction is to prevent lateral movement of the wheel upon the axle, thesquaring of the axle and of the bore of the hub elfectually preventingall tendency toward independent rotation of the wheel.

I have shown and described my invention as applied to a reversible wheelfor cars, but it will be understood that the same may be applied to anyform of wheel, and to wheels used for any purpose whatsoever Without inthe slightest degree departing from the spirit of my invention.

It will also be understood that although I have shown the wheel assecured with but two pins, as many pins may be used as is deemednecessary to the proper securing of the Wheel upon the axle.

What I claim is :v

1. In a wheel construction, the combination with a squared axle havingsockets formed in the faces thereof, of a wheel including a hub having asquared bore, a web having recesses therein, said hub and web beingprovided with radial bores the inner ends of which register with thesockets of the axle, while their outer ends terminate in the recesses ofthe web, pins passing through said bore and engaging said socket,

Copies of this patent may be obtained for five cents each, by addressingthe Commissioner of Patents and means for maintaining said pins inplace.

2. In a wheel construction, the combination with a squared axle havingsockets formed in the faces thereof, of a wheel including a hub having abore adapted to engage said axle and radial bores registering with thesockets of the axle, pins passed through said bores and engaging saidsockets, said wheel also having a web provided with bores adjacent theheads of said'pins, and pins passed through said latter bores andbearing against the first mentioned pin to maintain the same inposition.'

In testimony whereof, I ailix my signature, in presence of twowitnesses.
